Тема: TEA6320
TEA6320 представляет собой четырехканальный аудиопроцессор с цифровым управлением. TEA6320 преобразует стерео сигнал в четырех канальный (квадро). Аудиопроцессор позволяет производить регулировку уровня звука в каждом канале отдельно и во всех каналах одновременно, а также имеется возможность регулировать тембр по низким и высоким частотам.
